Open Source - XFS
Existing file systems for Linux entail significant limitations in scalability and stability. Unlike other journaled file systems currently under development, XFS is a mature technology that has been proven on thousands of IRIX systems for over six years. It is widely recognized as the industrys leading high-performance file system. SGI has now optimized XFS for Linux users, providing the same flexible, high-capacity, and reliable file system as before. Features such as instantaneous recovery from disk crashes and the ability to support extremely large disk farms will establish XFS as the production quality file system for Linux. Furthermore, porting XFS to Linux is helping advance some of the Linux kernel infrastructure such as the VM subsystem and the block device interface.
